• Performing a fuzzy search may retrieve terms with similar spellings: (( binary basic dose optimization algorithm ) OR ( binary mask arm optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary basic dose optimization algorithm ) OR ( binary mask arm optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary basic dose optimization algorithm ) OR ( binary mask arm optimization algorithm ))*.
